[NETFILTER] nf_conntrack: clean up to reduce size of 'struct nf_conn'
This patch moves all helper related data fields of 'struct nf_conn'
into a separate structure 'struct nf_conn_help'. This new structure
is only present in conntrack entries for which we actually have a
helper loaded.
Also, this patch cleans up the nf_conntrack 'features' mechanism to
resemble what the original idea was: Just glue the feature-specific
data structures at the end of 'struct nf_conn', and explicitly
re-calculate the pointer to it when needed rather than keeping
pointers around.
Saves 20 bytes per conntrack on my x86_64 box. A non-helped conntrack
is 276 bytes. We still need to save another 20 bytes in order to fit
into to target of 256bytes.
